Application iiled September 20,

To all whom t may Concern e y Be it known that l, Hanni J. Piinnins, a citizen 4of the United States, residing at Grand Rapids, Michigan, have invented certain new and useful improvements in Beverse-Gearv Mechanisms, of which the following is a specification. Y

This invention relates to improvements in reverse gear mechanisms.

The objects of this invention are: First, to provide an improved mechanism for actuating vthe clutch means without axial movement of the gear case or gear and other associated parts. Second, to provide an iinclutch mechanism whieh shallloe very coin- Third, to provide a strucwhich the adjustment in a reverse gear,

ture of reverse gear in is simple and effective. A

Further objects, and objects relating to details and economies of construction and operation will definitely appear from the detailed description to follow. y

I accomplish the4 objects of my invention described in the lfollowing specification. 1 y, y,

The invention is clearly defined and pointed out in the claims. t y

A structure which is a preferred embodiment of my invention is clearly illustrated in theV accompanying drawing, forming a part of this specification, inwhich; ,y

Figure I is a side elevation of my improved reverse gear mechanism, the driven shaft being broken awcytand detailsl of the support and the like being omitted. Fig, Il is a longitudinal vertical sectional .View through the mechanism, certain vparts being shown in full lines, the same being` shifted forl direct drive. Fig lll is a longitudinal sectional view similar to that of F ig, l1, the same being shifted fory the reverse drive. Fig. lV is a detail vertical sectional view through the sliding cone Ona line corresponding to line M4 of Fig. I.

In the drawing, similar reference char-` acters refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Considering the numbered parts of the drawing, z' is the driving shaft, .which may be the crank shaft of an engine, or any suitable power shaft, and is provided with a coupling flange 2.

3 is thedriven shaft which is provided with alconpling flange 4l.

5 the bearing block in which the driven shaft 3 is supported, provided with thrust bearings 6 and 7 at `each side, which are engaged by the flange @l and the collar 8 respectively, which collar and flange are pinned, keyed, vor otherwise secured to the said driven shaft. l

9 isa sleeve which turns on shaft?) and is provided with elongated spur gear teeth 10T at one end. On the other end of the shaft 9 is rigidly keyed a coupling flange 11. This flange is connected to flange 2 by bolts 12 and is held against thrust by a set screw or otherwise.` n l 13 is lthe gear cage carrying journal pins 14: on which are mounted or jurnaled the planetary pinions 15.

16 is the supporting ring at the inner ends of the pins 14 and carried by bridge bars (not shown) of the gearcage 13.

isthe outer casing within which is disposed the gear cage 13, the 'same being secured thereto and flanged to constitute the coverA for one end. lThe casing v17 is dis,- posed within,,andsupp'orted by the reverse brake' 1S. rThe casing 17 is extended into a hub 19 integral therewith which is suitably recessed for the accommodation of the actuating pins for the clutch hereinafter to be described. .l v

An in ernal orbit gear y20 is provided which is disposed tomesh with the planetary piniens 15 and extends beyond the same to forma chamber to receive the clutch. The crow/'n.721 of the gear is perforated for the passage of the axially ing pins hereafter to be described. rlhe crown 21 is extended into a hub r22 and i's securely keyed and pinned to .the shaft 3.

A.' frictional clutch comprising disks 23, which` alternately are notched to engage the spur gear 9 or the internal lgear 20, are disposed within the chamber of the crown 21 of internal gear 2O and coact with the ring 16 at the inner end of the gear Cage.

In the perforations of the crown 21 of the gear 2O longitudinally slide the axially disposed clutch actuating pins 25. These pins bear against thrust ring 26. The thrustring 26 is disposed betweenl hub 19 of casing 17v and the vhub 22 of the internal gear 20. The thrust ring is suitably keyed to hub 22 and adapted to slide back and forth disposed clutch actuat-I 2. In a reverse gear mechanism, the combination of a driving shaft, a driven shaft, a planetary gear cage with pinions therein carried by the driven shaft, a brake drum casing disposed around the same, an orbit gear with a hub on said driven shaft disposed within the casing and meshing with the planetary gear pinions within said case, a disk clutch disposed within the crown of said gear to coact between the same and the said planetary gear cage, thrust pins disposed in perforations through the crown of said gear, a thrust collar disposed on the hub of said orbit gear, an adjustable screw threaded bearing ring on the said thrust ring, a collar with toggle levers thereon, a sliding cone journaled on the driven shaft to actuate the toggle levers, a control lever for controlling said cone, coacting for the purpose specified.

3. .ln a reverse gear mechanism', the combination of a driving shaft, a driven shaft, a planetary gear cage with pinions therein carried by the driven shaft, a brake drum casing disposed around the saine, an orbit gear with a hub on said driven shaft disposed within the casing and meshing with the planetary gear pinions within said case, a dislr clutch disposed within the crown of said gear to coact between the same and the said planetary gear cage, thrust pins disposed in perforations through the crown of said gear, a thrust collar with an internal Copies of this patent may be obtained for ve cents each, by addressing the annular recess disposed on the hub of said orbit gear, a spring within the recess in said collar disposed to react against said crown, a collar with toggle levers thereon, a sliding cone journaled on the driven shaft to actuate the toggle levers, a control lever for controlling said cone, coacting for the purpose specified.

4. ln a reverse gear mechanism, the combination of a driving shaft, a driven shaft, a planetary gear with reverse brake and clutch, a thrust ring for actuating said clutch, a screw threaded bearing ring on said thrust ring, a collar with toggle levers fulcrumed to act on said thrust ring, a locking finger carried by said collar for loclring the thrust ring in adjusted position, as specified.

5. In a reverse gear mechanism, the combination of a driving shaft, a driven shaft, a planetary gear with reverse brake and clutch, a recessed thrust ring for actuating said clutch, a spiral spring disposed within Y said recess to force said ring outward, a control lever and connections to act on said thrust ring, as specified.

In witness whereof, l have hereunto set my hand and seal in the presence of two witnesses.
